Naftifin Pharmacodynamics
Naftifin is an antifungal agent for external use, belonging to the class of allilamines. The mechanism of action is associated with inhibition of squalene-2,3-epoxidase, which leads to a decrease in the formation of ergosterol, which is a part of the cell wall of the fungus. Naftifin, affecting squalene epoxidase, does not affect the cytochrome P-450 system.
It is active against dermatophytes such as Trichophyton, Epidermophyton, Microsporum, yeast and yeast-like fungi (Candida spp., Pityrosporum), mold fungi (Aspergillus spp.) and other fungi (such as Sporothrix schenckii). Against dermatophytes and aspergillus naphthifin acts fungicidal. Against yeast fungi the drug exhibits fungicidal or fungistatic activity depending on the strain of the microorganism. It has antibacterial activity against Gram-positive and Gram-negative microorganisms causing secondary bacterial infections. It has anti-inflammatory action, which contributes to the rapid disappearance of inflammatory symptoms, especially itching.
